Sins ruin hearts:

[a_stranger]

It has been reported by Imam Ahmad in Al-Musnad and Al-Tirmithi in Sunan that Abu Hurairah narrated that the Prophet of Allah salla Allah alaihi wa sallam said, “When the believer commits sin, a black spot appears on his heart. If he repents and gives up that sin and seeks forgiveness, his heart will be polished. But if (the sin) increases, (the black spot) increases. That is the raan which Allah mentions in His Book: ‘Nay! But on their hearts is the Raan (covering of sins and evil deeds) which they used to earn’ .” Al-Tirmithi said that it is sahih (authentic).

One of the scholars said: When the body is uncovered from its clothes, it becomes weak, but when the sins of the heart decrease (i.e. it is uncovered from the Raan), its tears flow quickly.

‘Abdullah Bin Al-Mubarak said:

I think sins kill the heart

Purity of intention is important:


'Umar Ibn Al-Khattaab narrated that the Messenger of Allaah said: "The reward of deeds depends upon the intention and every person will get the reward according to what he has intended…” [Al-Bukhaari]
